STUDIES ELATED TO 0L.M

Bureau o f Land Management Recreation Areas

The Federal Land Po l i cy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey t o assess ce r t a i n areas t o determine t h e i r mineral resource potential, if any. Results must be made ava i lab le t o the pub l i c and be submitted t o the President and the Congress, This repor t presents the resu l t s o f a geochemical survey o f the Livengood and western 113 of the C i r c l e quadrangles, Alaska.

INTROWCTION

From 1974-1979, the U.S. Atomic Energy Comnission (subsequently the Energy Resource Development Admini s t r u t i on and the Department of Energy) funded the "Hydrogeochemi ca l and Stream Sediment Reconnai ssance" pro jec t as p a r t of the National Uranium Resource Evaluation (NURE) program t o assess uranium resources i n the United States (Weaver and others, 1983). I n ant ic ipat ion o f mineral resource studies o f the Livengood 1" x 3" quadrangle and the White Mountains National Recreation Area i n the Livengood and C i rc le quadrangles, the U.S. Geological Survey reanalyzed the samples col lected i n the Livengood a d western 9 111 o f the C i rc le lo x 3" quadrangles, a t o t a l area o f about 7,800 m i (20,200 km ). The purpose o f reanalyzing the NURE samples was t o estab l ish a consistent ana ly t i ca l base f o r in tegra t ing the resul ts o f more recent sampling, and thereby provide a greater sampling densi ty than would otherwise be avai lable,

The Livengood 1' x 3" quadrangle i s i n the east-central pa r t of Alaska from 65" t o 66" north la t i tude , and from 147' t o 150" west longitude, The C i rc le quadrangle l i e s due east o f the Livengood quadrangle, and the western 1/3 o f the quadrangle (146"-147") i s included i n t h i s report. The E l l i o t and Dalton Highways traverse the Livengood quadrangle from southeast t o northwest. The Steese Highway crosses the southeastern Livengood quadrangle and continues northeasterly across the C i r c l e quadrangle ( f i g , 1).

The area comprises a northeasterly trending sequence o f Precambrian, Paleozoic, and Mesozoic sedimentary and rnetasedimentary rocks i n the north- western par t of the Yukon-Tanana Upland. These rocks consist mostly o f Cambrian and Ordovician quartz i te, a rg i l li te, slate, and minor 1 imestone; Ordovician, Si lur ian, and Devonian limestone, dolostone and chert; Jurassic- Cretaceous conglomerate, graywacke, and quar tz i te (Chapman and others, 1971). Cretaceous-Tertiary age g r a n i t i c t o granodior i t ic int rusions and some syenite form topographic highs a t Cache Mountain and V ic to r ia Mountain (Weber and others, 1985). Quaternary loess blankets mrch of the southern 1/3 o f the area, and a1 l uv i a l deposits fi 11 the major drainage courses. Outcrops are scarce throughout most o f the area, except where r e l i e f i s high. The study area l i e s w i th in a s t r u c t u r a l l y deformed block between the T in t ina f a u l t system t o the north and the Denali fau l t system t o the south. The Paleozoic and Mesozoic rocks o f the area generally s t r i k e northeast and d i p northwest o r are overturned and dipping steeply southwest (Weber, wr i t ten commun., 1986).

The topographic r e l i e f i n the area o f t h i s report i s about 5,000 f t (1525 m), wi th a maximum e levat ion o f 5,286 ft (1611 m) a t M t . Prindle. The White Mountains form a topographic high on the east and are drained by Beaver Creek on the south, west, and north, The remainder of the Livengood quadrangle l i e s w i th in the drainages of the Yukon and Tolovana Rivers, separated by the Sawtooth Mountains on the west side o f the Livengood quadrangle. The cl imate o f the area i s ar id t o semiarid. The h igh- la t i tude tundra proh ib i ts ground-water seepage and enhances surface runoff.

Sample Wdia

Analyses o f the stream-sediment samples represent the chemistry o f the rock mater ia l eroded from the drainage basin upstream from each sample s i te . Such information i s useful i n i den t i f y i ng those basins which contain concentrations o f elements t ha t may be re la ted t o mineral deposits.

Sarple Col lect ion and Analysis

Samples from 1,010 s i t e s were reanalyzed f o r t h i s repor t (p late 1). These samples represent f i ne-grained sediment co l lec ted from the ac t i ve po r t i on o f small-order stream drainages, The avera e sample density f o r t h i s 3 group o f samples i s one sample per 7.7 m i 2 (19.9 k ) Of the o r i g i na l NURE sarnple set, 5 samples d i d not have s u f f i c i e n t mater ia l remaining f o r analysis and are not included here.

The minus-100-mesh (0.15-mn) f rac t ion of the stream-sediment samples t h a t remained a f t e r analysis by Los Alamos Sc ien t i f i c Laboratory was retained i n archival storage. The archived por t ion of these samples was analyzed fo r 31 elements using a semiquantitative. d i rect-current arc emission spectrographic method (Grimes and Marranzino, 1968). The elements analyzed and t h e i r lower l i m i t s o f determination are l i s t e d i n tab le 1, Spectrographic r esu l t s were obtained by visual comparison o f spectra derived from the sample against spectra obtained from standards made from pure 0x1 des and carbonates. Standard concentrations are geometrically spaced over any given order of magnitude o f concentration as follows: 100, 50, 20, 10, and so forth. Samples whose concentrations are estimated t o f a l l between those values are assigned values o f 70, 30, 15, and so forth. The prec is ion o f the ana l y t i ca l method i s approximately p lus o r minus one repor t ing in te rva l a t the 83 percent confidence leve l and plus o r minus two report ing in te rva ls a t the 96 percent confidence 1 eve1 (Motooka and Grimes, 1976). Analyt ical data f o r samples from the Livengood and western 113 of the C i rc le quadrangles are l i s t e d i n t ab le 2.

ROCK ANALYSIS STORAGE SYSTEM

Upon completion of a l l ana ly t ica l work, the ana ly t i ca l resu l t s were entered i n t o a computer-based f i l e ca l led Rock Analysis Storage System (RASS) . This data base contains both descr ip t ive geological information and analy t ica l data. Any o r a11 o f t h i s information may be re t r ieved and converted t o a binary form (STATPAC) for computerized s t a t i s t i c a l analysis or pub1 i c a t i on (VanTrump and M i esch, 1977).

DESCRIPTION OF DATA TABLES

Table 2 l i s t s the resu l t s o f analyses f o r the samples o f stream sediment. The data are arranged so tha t column 1 contains the NURE-assigned sample numbers. These numbers correspond t o the numbers shown on the s i t e locat ion map (p la te 1). Columns i n which the element headings show the l e t t e r "s" below the element symbol are emission spectrographic analyses. A l e t t e r 'N" i n the tables indicates that a given element was laoked f o r but not detected a t the lower l i m i t o f determination shown fo r tha t element i n tab le 1, I f an element was observed but was below the lowest repor t ing value, a " less than" symbol (

o f determination. I f an e lemnt was observed but was above the highest repor t ing value, a "greater than" symbol (>) was entered i n the tables i n f r o n t o f the upper l i m i t o f determination, Because o f the formatt ing used i n the computer program t h a t produced tab le 2, some o f the elements l i s t e d in these tables (Fe, Mg, Ca, T i , Ag, and Be) carry one o r more nonsignif icant zeros t o the r l g h t o f the s lgn i f i can t d i g i t s . The analysts d i d not determine these elements t o the accuracy suggested by the ext ra zeros.

The spectrographic deteminations f o r Au, Cd, and Sb were a l l below the lower l i m i t s o f determinations shown i n tab le 1; consequently, the columns f o r these elements have been deleted from tab le 2.
